During a talk at the 2017 World Government Summit, none other than Elon Musk — the SpaceX and Tesla CEO and stock market manipulating wunderkind — revealed the one behavioral interview question that he asks all of his prospective employees.
According to Musk, regardless of an applicant’s education or the experience listed on their resume, this one question helps him root out the liars and charlatans from those who have demonstrated “evidence of exceptional ability.”
“If there’s a track record of exceptional achievement,” said Musk, “then it’s likely that that will continue into the future.”
Elon Musk’s Favorite Behavioral Interview Question
For those who are new to the concept, a behavioral interview question is a question that centers on a candidate’s previous performance as a potential indicator of how they will perform in the future. Compare this to traditional interview questions, which tend to be open ended or leave too much room for puffery.
The framework of an effective behavioral interview question essentially boils down to the phrase “Tell me about a time when you…” or other variations of the same, including:
- Can you give me an example of…
- Explain what it was like to…
- Describe a situation in which you…
So, what was the one question that Musk asks all of his interviewees? According to the Wizard of Odd himself, he asks each and every candidate the following:
Tell me about some of the most difficult problems you worked on and how you solved them.
That’s it! And why is this particular interview question Mr. Musk’s favorite one to ask? Well, as he explains it, “the people who really solved the problem know exactly how they solved it. They know and can describe the little details.”
The Devil’s in the Details
It all comes down to the details!
The thinking goes that, anyone can claim to have done great things. But, when someone is able to explain the specifics surrounding how they actually managed to solve a particular problem, it sets them apart from the pretenders.
The fakers will have a hard time explaining exactly what it is that they did. The doers, on the other hand, won’t stumble while trying to offer an explanation.
Science Explains How Behavioral Interviewing Works
Cody Porter, Senior Teaching Fellow in Psychology and Offending Behavior at the University of Portsmouth, studies lying and ways to detect it. In an article she wrote for The Conversation, Porter outlines a lie-detection technique she calls “Asymmetric Information Management (AIM).” In that article, she explains:
At its core, (AIM) is designed to provide suspects with a clear means to demonstrate their innocence or guilt to investigators by providing detailed information. Small details are the lifeblood of forensic investigations and can provide investigators with facts to check and witnesses to question. Importantly, longer, more detailed statements typically contain more clues to a deception than short statements.
Though this explanation is more geared toward professional investigators, the same holds true for business owners and managers during job interviews. To get the best and most actionable information possible from your interviewees — and to force the fakers to reveal themselves during the interview process — ask them to go into detail when answering your questions.
Or, as it was described in a paper published in the June 2020 edition of The Journal of Applied Research in Memory and Cognition (on which Porter was an author), “interview protocols to improve lie-detection should (a) encourage forthcoming verbal strategies from truth tellers and (b) encourage withholding verbal strategies from liars.”
